Reports have circulated that Manchester United had an €85 million bid for the young attacker rejected by the Ligue 1 leaders, who are said to want upwards of €110m for the 18-year-old France international.

Vasilyev, however, has rejected the notion that the forward could be sold.

“Mbappe has no price,” he told Gazzetta dello Sport. “He is like a son.

“We are proud that he is already at this level with our jersey. We would like him to stay and I think he also wants that.”

Indeed, Vasilyev is optimistic that Monaco will be able to retain much of the squad that has reached the Champions League semi-final, although he did admit that there will be changes. These will not, however, be imposed on the club.

“A couple of players will be sold, but we do not have to do it. We have never prevented anyone from going. But the player must ask us and a right offer is required,” he emphasised.

As well as a European tie against Juventus to look forward to, the Stade Louis II outfit are closing in on the league title, with only six points required from their last four games to wrest the crown away from Paris Saint-Germain.
